BUTTON.

SPECIFICATION forming part of Letters Patent No. 458,094, dated August18, 1891.

Application led April 19, 1890. Serial No. 348,723. (No model.)

To @ZZ whom it may concern:

Be it known that I, J ULIUs D. BRAINARD, a citizen of the United States,residing at St. Paul, in the county of Ramsey and State of Minnesota,have invented certain new and useful Improvements in Detachable Buttons,of which the following is a specification.

This invention relates to detachable buttons; and it consists in theconstruction, cornbination, and arrangement of parts, as hereinaftershown and described, and specifically pointed out in the claim.

In the drawings, Figure lis a View of abutton with the outer covering insection, show# ing the internal construction. Fig. 2 is across-sectional View on the line XX of Fig. 1. Fig. 3 is a perspectiveView of the spring-supporting plate removed. Fig. et is a perspectiveView of the detachable shank removed.

The covering and body of the button may be of any suitable constructionor material that will permit of the insertion of the novel devices forsupporting the detachable shank; but for the purpose of illustration Ihave shown it composed of the back plate A and front plate A2, connectedby a rim A3 rolled around their edges, Which is an ordinary con'-struction.

Inserted into the interior of the buttonis a plate or disk B, having twobent-up portions ct', around which abent-Wire spring b is held, the freeends b2 h3 of the spring resting on either side of a central opening d',as shown in Fig. l. This opening d is circular in outline, except on oneside, Where a recess d2 is formed in it, this configuration also beingpresent in the disk B.

D represents the detachable shank having a head D2, the shankcorresponding to the opening d', and with a lug` c on the shankcorresponding to the cavity d2, so that the shank may be inserted freelythrough the openings both in the back A and the disk B. The recess d2will be on the same side of the opening d as the ends b2 b3 of thespring h',

the spring and its end offering ne resistance to theinsertion of theshank. When,` however, the shank is inserted and turned half- Wayaround, the lug e will push the end 122er b3 to one side,`as shown inFig. l, which represents the shank being inserted and turned, so as topush the end h2 to one side, until it passes its influence, when thereaction of the spring Will cause the end to return to its formerposition. The shank will then be removable only by being turned untilthe lug e is opposite the recess d2; but this will necessitate theforcing of oneof the ends b2 or b3 to one side again, an act which willnever occur by using the button, as the revolving force necessary toaccomplish this is never imparted to it While in use.

The invention is applicable to any form or style of button, either otthe most common kind used on mens clot-hing, the finest kind of sleeveand collar buttons, or upon fancy buttons for ladies use.

I-Iaving thus described my invention, WhatI claim as new is- In adetachable button, the outer shell A A2, having the slotted opening d d2through its rear face and with the inner disk B supported therein,bent-up portions d' on the edge of said inner disk, spring h', restingupon said disk and supported thereon by said bent-up portions, and withits ends h2 b3 bentinward and lying alongside said slotted opening, incombination with the shank D, having the projection e, and adapted to beinserted into said slotted opening, and when turned to compress saidspring and be retained in place thereby, substantially as and for thepurpose set forth.

In testimony whereof I have hereunto set my hand in the presence ot twosubscribing witnesses.

JULIUS D. BRAINARD.
